Problems solved by technology

Due to the poor biodegradability of mineral oil and synthetic hydrocarbons, the discharged waste liquid stays in water and land for a long time, seriously polluting the environment; the compounded additives contain toxic substances such as oxidized paraffin and sodium nitrite, which endanger human health
In recent years, many domestic manufacturers have launched environmentally friendly cutting fluid products (but there is no authoritative test report), but due to unsatisfactory lubrication performance, high friction coefficient, and high tapping torque value, they are not favored by the market.

Abstract

The invention discloses high performance biodegradation type metal machining protection liquid, which is composed of high polymer carboxylic acid, organic amine, higher alcohol, a surfactant, plant oil or synthetic lubrication grease, pure water, an antifoaming agent and preservative or bacteriacide. The high performance biodegradation type metal machining protection liquid is good in biodegradable performance. A formula of the high performance biodegradation type metal machining protection liquid can be designed by choosing the plant oil or synthetic ester and other additives. Biochemical oxygen demand (BOD) / chemical oxygen demand (COD) of 3.3% of diluent is larger than or equal to 1.0, so that the high performance biodegradation type metal machining protection liquid is excellent in lubrication performance. The frictional factor mu of the 3.3% of diluent is smaller than or equal to 0.03, and tapping torque of the 3.3% of diluent is smaller than or equal to 400N*cm, so that the high performance biodegradation type metal machining protection liquid is safe, hygienic and reliable in quality. The biological median lethal dose LD50 of the high performance biodegradation type metal machining protection liquid is larger than or equal to 5,000mg / kg, the medical lethal concentration LC50 is larger than or equal to 5,000mg / m<3>, respiratory tract mucous membrane irritation is smaller than or equal to 1 level, and the high performance biodegradation type metal machining protection liquid is friendly to human and environment.

Description

technical field [0001] The invention relates to a metal processing protective fluid. Background technique [0002] Traditional metal processing protection fluids are generally made of mineral oil or synthetic hydrocarbon with excellent lubricating properties as base oil, compounded with phosphorus extreme pressure agent, rust inhibitor, surfactant and other additives. Due to the poor biodegradability of mineral oil and synthetic hydrocarbons, the discharged waste liquid stays in water and land for a long time, seriously polluting the environment; the compounded additives contain toxic substances such as oxidized paraffin and sodium nitrite, which endanger human health. In recent years, many domestic manufacturers have launched environmentally friendly cutting fluid products (but there is no authoritative test report), but due to unsatisfactory lubrication performance, high friction coefficient, and high tapping torque value, they are not favored by the market.
